【摘要】 进海路是为了开发丰富的滩海石油资源而修筑的联系陆地与人工岛的纽带。极浅海滩涂地带受潮汐影响,水陆界伸缩很大,因此进海路建设具有费用高、风险大、工期长、维修费用高的特点。漫水路设计是近年来新型的筑路方式,其路面允许潮水淹没和通过,潮水过后即可恢复通车使用。进海路路堤堤高是影响进海路堤工程建设总费用的关键因素,其合理设计对于保证进海路通行天数、降低工程建设总费用是至关重要的。本文采用遗传算法,结合全寿命周期成本理论,建立了进海路堤堤高多目标优化设计模型,并对渤海海域某工程地的进海路堤进行优化设计,结果表明:利用该方法具有优越性,可以节省工程建设资金。更多还原

【Abstract】 Jetty road is the link of onshore to artificial island for marine oil exploitation and production. Because of special terrain conditions of shallow beach area affected by tide,the project construction of jetty road has characteristics of higher investment,higher degree of risk,longer construction duration and higher maintenance costs.Overflow road has been developed recently with height lower than the highest water level.The roads are different from usual roads in that overflow is allowed during high tide.The most important factor that influences the cost is the height of jetty road.To assure reasona- ble working days,maintain quality and reduce the project cost,it is important to determine a proper road height.Combining with full life-cycle cost theory,this paper presents a genetic algorithms(GAs) model for multi-objective optimistic design of jetty road height.The model is applied to oil field around Bohai Sea,and the numerical results show that the optimistic models perform well for optimistic prob- lem and reduce the engineering cost.更多还原
